VENTILATOR.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application led April 3, 1908. Serial No. 424,975.

To all whom it may concern:

Be it known that I, FRANK EMMENEGGER, a citizen of the United States, residing at St. Louis, in the county of St. Louis City and State of Missouri, have invented new and useful Improvements in Ventilators, of which the following is a specification.

This invention relates to an improvement in ventilators for buildings, and the object of the invention is to provide a simple device of this character which may be readily and easily applied to the pipe opening of a chimney flue, and which is inclined so as to prevent rain or soot falling down the chimney flue from entering the room.

Another object of the invention is to provide a ventilator for chimneys of buildings which is provided with a valve or damper whereby the entrance of air may be accurately regulated. l

With these and other objects in view the invention resides in the novel combination and construction of elements hereinafter fully described and claimed.

In the drawing,-Figure 1 is a vertical section of a chimney flue with my improved ventilator in position thereon. Fig. 2 is a rear elevation of my improvement, and F 3 is a fragmentary section taken up'on the line 8 3 of Fig. 2.

My invention is primarily intended to occupy the pipe opening of a chimney flue during the heated seasons when the customary heating stove has been removed, but it is of course obvious that a separate opening may be provided in the chimney and the ventilator used as a permanent attachment.

In the drawing the numeral 1 designates a chimney flue provided with a customary pipe opening 2, adapted to receive the inwardly projecting fingers 3 of a collar or disk 4. This disk 4 is preferably constructed of resilient material and has the ngers 3 integrally formed upon its inner periphery. The fingers being of spring material are adapted to tightly engage with the pipe opening of the chimney and to hold the disk in an immovable position upon the chimney breast. The disk 4 is also provided with a series of openings 5, adapted for the reception of fingers 6 formed upon an inclined thimble 7. These lingers 6 of the thimble are bent upon the inner face of the disk 4L as clearly shown in Fig. 3 of the drawing, thus effectively securing the disk and thimble together.

A valve or damper 8 is provided within the thimble 7 having the handle 9 and a disk or washer 10, between which and the thimble is interposed a helical spring 1l, which serves to normally hold the damper against the lower face of the thimble 7 at any required angle, thus effectively providing means for regulating the entrance of air through the thimble and securing the damper at any required angle.

From the foregoing description it will be seen that I have provided a cheap and efficient ventilator for buildings, which may easily be applied to or detached from the pipe hole of a chimney breast.

l/Vhile I have described the preferred embodiment of my invention changes in the precise construction may be resorted to without departing from the spirit or sacrificing any of its advantages.

Having thus described the invention what is claimed as new, is

In a device for t-he purpose set forth, the combination with a chimney provided with a pipe opening of a diskshaped member having a central opening, resilient fingers upon the disk projecting inwardly from the opening thereof, the disk provided upon its face with spaced slits, a thimble having fingers adapted to be inserted within the slits of the disk and to be bent to retain the thimble upon the disk, said thimble comprising a pipe section cut diagonally to provide a short upper surface and a comparatively longer lower surface, and a spring retained valve within the thimble.

In testimony whereof I aiiiX my signature in presence of two witnesses.

FRANK EMMENEGGER.
